xsdcpp codegen fails: cannot resolve group oreTradeData

Running ./projects/ores.codegen/scripts/xsdcpp_generate_ore.sh with the local /home/marco/Development/xsdcpp/build/src/xsdcpp binary (xsdcpp 1.0.3) against external/ore/xsd/input.xsd fails:

error: Could not find group 'oreTradeData'

Confirmed via a clean A/B test (git stash the external/ore/xsd/ sync, re-run, restore) that this happens identically against BOTH the external/ore/xsd/input.xsd content already committed on main before this session's ORE version bump AND the freshly-synced 1.8.16.0 version – so this is a pre-existing local environment/tool-version issue, not something the vendored XSD content update introduced. The group is defined (external/ore/xsd/instruments.xsd:6, <xs:group name"oreTradeData">=) and referenced correctly through the same import chain xsdcpp's own log shows it walking (input.xsd -> instruments.xsd -> … -> historicalreturnconfig.xsd, erroring right after) – looks like a genuine resolution bug in this xsdcpp build, or a version mismatch between this local xsdcpp checkout and whatever version last successfully generated the projects/ores.ore/include/ores.ore/domain/domain.hpp=/=domain.cpp currently committed on main.

Blocks regenerating ores.ore's domain types after external/ore/xsd/ is refreshed (see the IR curve seed-data capture-adjacent work: the ORE Engine binary/examples/XSD version-bump task). Left projects/ores.ore/include/ores.ore/domain/domain.hpp and domain.cpp UNCHANGED (still generated from the pre-bump schema) rather than attempt a workaround – xsdcpp is a separate tool/repo (~/Development/xsdcpp), not something to patch blind. Needs either rebuilding xsdcpp from its current upstream source (this local build may predate a fix), or investigating the group-resolution bug directly in xsdcpp's own source if it's still broken on a fresh build.

• Error reproduction: ./projects/ores.codegen/scripts/xsdcpp_generate_ore.sh (needs xsdcpp on PATH)
• Group definition: external/ore/xsd/instruments.xsd:6
• Group references: external/ore/xsd/input.xsd (x3), external/ore/xsd/referencedata.xsd:224
• Local xsdcpp checkout: ~/Development/xsdcpp (xsdcpp --version reports 1.0.3)
• Consumer: projects/ores.ore/include/ores.ore/domain/domain.hpp, projects/ores.ore/src/domain/domain.cpp
